google maps - FETCH_ERROR on parse KMZ in WEB -
i have application features dynamic kmz on map. kmz needs updated every 60 seconds, wherefore url uses versioning feature: "?v=201606011903". earlier week kmz stopped appearing on map , error api returns "fetch_error".
i'm intrigued as:
- there have been no changes in application;
- the generation of kmz working properly;
- tested kmz generated in feedvalidator , result valid kml 2.2 feed;
curiosity: apparently there delay in acquisition or parse of kmz api. if try same kmz again after 3 minutes api returns correct results.
doubt: there maximum time download or parse of kmz api?
script test:
- first change value of "v" , run. error "fetch_error" appear.
- wait 3 minutes , run same code (as same parameter). kmz should appear correctly.

thank's!
it can caused size , complexity restrictions kml rendering, noted limits subject change @ time.
maximum fetched file size (raw kml, raw georss, or compressed kmz)
3mbmaximum uncompressed kml file size
10mbmaximum number of network links
10maximum number of total document-wide features
1,000number of kml layers
there limit on number of kml layers can displayed on single google map. if exceed limit, none of layers appear on map. limit based on combination of number of kmllayer classes created , total length of urls used create layers.
aside restrictions, common issues can encountered in rendering kml/kmz , tips resolve these issues can found in kml best practice , kml errata.
